2600K @ 5GHZ, How common is it really???

[Acanthus]

Sig. But it is external watercooling.

 

[PreferLinux]

sure you are

Ill paypal 100 bucks if you make a video of your chip booting on a 57x multy into windows and running load with just 1.55.

I dont think there has ever been a 57x multy chip ever seen with liquid nitrogen cooling and 1.7 volts

some are lucky and have 55x chips and run the bclk at 104 for 5.7ghz runs

Multiplier: 58x http://hwbot.org/submission/2177360_nickshih_cpu_frequency_core_i7_2600k_6044.3_mhz He also had one with a 59x multiplier.

Very good, but you know you're doing a lot of damage to your CPU. I wouldn't think in a million years of doing that to one of the world's fastest desktop CPUs, which happens to also cost a healthy $600. You know if you keep running it like that you'll end up with a heavily degraded chip in less than a year, which could mean something like a measly 4GHz will be out of reach.

True. I actually had an RMA approved from Intel for an exchange for C2 stepping, but I'm not taking it because I've voided the warranty with the massive voltage OCing I've done on this chip.

I do have the PTPP though, so I guess I can just keep giving it more voltage to maintain the clock I want and if it dies, I can RMA it.

I found the sweetspot (balancing performance vs temperature vs voltage) for my 2600k to be 4.4Ghz.

4.4GHz @ v1.27 = Max Temp of 62C... its gonna live forever.

5.0GHz in Crysis benchmarking only yielded an additional 2 fps over 4.4Ghz. Sure, thats only one game, but after seeing the results i decided to abandon my 5.0Ghz ambitions.

-where's the load ?

I just went from E8500 to i2600K.

Huge difference.

I was at 4ghz with my E8500.

Have not even OC-ed the 2600k yet.

very commendable that you go for a practical overclock, a lot of people just crank up the volts and see where it takes them, not caring that their power consumption is far higher than it could be at a performance level they'd still be happy with, not that they even need the 5GHz to begin with, many just do it for the epeen.

its gonna live forever.

Ivy is only a few months away, I don't need mine to live forever (not that I give mine insane volts, I'm only 4.7GHz @ 1.36v)

5.0GHz in Crysis benchmarking only yielded an additional 2 fps over 4.4Ghz. Sure, thats only one game, but after seeing the results i decided to abandon my 5.0Ghz ambitions.

well, Crysis is GPU limited, so that's not surprising, try live streaming while playing Crisis

I know I appreciate all the CPU power I can get whenever I livestream. I really wanted to upgrade to s2011 to finally go beyond quadcore, but X79 was such a disappointment I held off taking that plunge.

 

[blackened23]

people dont know that almost every chip will do 5+ghz it just takes a lot of volts to push them up there.

I can bench at 5200 mhz but I dont like jaming 1.55 volts into this chip but it will be stable given enough volts.

people get scared when they see 70c temps even tho the chip wont throttle until 99c.

I can almost bet that most chips with the right board will hit 5ghz at 1.5 volts

I won't lie , I hate agreeing with grkM3 about ANYTHING but most chips will not do 5ghz at less than 1.5vcore. At least, not prime95 stable. You might be able to boot into windows but it won't be prime95 stable in all likelihood. Are there exceptions? Sure, but my experience is that 5ghz requires a ton of juice.

You can do it on a LOT of chips but you will have to put some extreme voltage through it. I can do 5ghz with 1.49 vcore. No way am I doing that 24/7

Intel won't know if you overclocked/volted, so long as your chip still works I wouldn't have a problem sending it in for the stepping it really should have shipped with in the first place.

Though you might get a weaker chip, or stronger one.. but I'd worry more about getting a weaker one and if you don't need the vt-d or whatever the stepping fixed it's probably not worth it.

1.78v! I think I smell burning hair.

It's all about where you hit that wall that requires huge voltage increases to get past. For me it is 4.7, which I can do with 1.34. After that it's about .05 for every 100mhz. Mobo makes a difference too. I had a gigabyte x79 board at first that needed 1.39 just to do 4.5 and could not get pasr without major voltage. My current board is so much better.

Did you read the guy I quoted and asked for proof?

He said 57x at 1.3 volts and air cooling

thanks for letting me know that at 1.730 volts and -80c liquid nitrogen cooling can get the chip to post lol

My chip needs 1.560 for around 5.1-5.2ghz and to get to 5.3 I need over 1.6 volts for it to prime without a hard lock.

 

[Kenmitch]

This is as crazy as I got with my 2700k no HT lasted about 30 minutes till go a bsod surfing web at the same time.

5ghz no HT at 1.4v or less I'd be happy.

Chip is on water temps still crazy tho.

[grkM3]

Intels max programed multy is 57x look it up

Just posting to report that a year of 1.45v in my 2600k for 4.8GHz is still humming along a year later.

Have had my 2600k at 4.8GHz using 1.45v (Prime stable) since 7/26/2011. Does 5GHz with 1.49-1.51v 4c/4t. Motherboard is an ASRock Z68 Extreme7. Pretty much, any 2500k and 2600k can do 5GHz with the right cooling and motherboard.

As for LGA 2011, I also had a 3930K with an ASRock Fatal1ty Pro motherboard and it did 4.75GHz stable with 1.35v (load) but required a ton more for 5GHz (1.45v, hot hot hot). That setup ended up being sold as I saw no real benefit having that over a 2600K, all I do is play games, browse the web, and do light c# coding.

BTW: There is a link to a video of my 3930k build in my sig.

 

[SickBeast]

I can hit 5ghz stable on my 2500k but it requires 1.5v. Considering I'm GPU limited for most of my demanding tasks, I'm more comfortable running at 4.5ghz near stock voltage.

People say that 1.5v is not a safe everyday voltage but IMO it's probably fine. Yes, the chip will degrade faster, but I usually upgrade every couple of years anyhow.

 

[Danno21]

On my 2500k, I can hit 4.8Ghz with a vcore of 1.39 and LLC at high with max IBT temps of 78c and gaming temps of 50-60c, but above that and it takes too much voltage for my liking.

 

[FalseChristian]

I'm running an i5 2500K at 4.5GHz for everyday gaming using 1.275 volts. I have benchmarked at 5GHz but the voltage is at 1.525 and the heat generated is enormous. 4.5GHz is more than enough CPU power for everyday gaming.
